Resources: Developing on the Kovan testnet

[Justin]

To aid developers, Proof of Humanity is also running on the Kovan Ethereum testnet.

Contracts:

• PoH: 0x73bcce92806bce146102c44c4d9c3b9b9d745794
• UBI: 0xDdAdE19B13833d1bF52c1fe1352d41A8DD9fE8C9

Test Humans:

• A Kovan instance of the webapp is running here: app-kovan.poh.dev
• This instance is patched so that new submissions are immediately registered (no vouching, deposit or waiting period).
  • After accepting the wallet transaction, wait for a second transaction and accept that. The first is registration, the second is to start accruing UBI

Other resources:

• PoH REST offers a Kovan deployment: api-kovan.poh.dev
• Dummy contracts: Example contracts to use in-place of PoH/UBI (an alternative development approach used by the Humanitweet project)
• Having trouble finding Kovan ETH? See this reddit post

Shoutout to Kleros (Aleix and @clesaege) for support, including building the proxy governor contract.

Update: the web app (proof-of-humanity-web) now has a Kovan deployment: app-kovan.poh.dev

[Justin]

Update: The Kovan webapp instance is now patched so that new submissions are immediately registered (no vouching, deposit or waiting period).

• The patch changes out the normal addSubmission for addHumans on the proxy governor.
• The proxy governor contract allows anyone on Kovan to manually register humans: 0xF5FcFD161C1a5036a4a9Dec9060FD5f769061De7

Hi, the Dummy Contracts link is dead, looks like its moved to: posta/posta-contracts/contracts at main · JuanuMusic/posta · GitHub

[Justin]

Thanks, it was caused by the repo rename to Posta. Fixed!

FYI, I’ve deployed the ProofOfHumanityProxy.sol contract to the Kovan network here: 0xb270ee8830de2b8b184712b278610bb5610fa69e.

I needed to test the integration with PoH on the Kovan testnet, specifically calling the isRegistered function directly from the proxy contract and not from the main one. That is possible on mainnet but it wasn’t on Kovan as far as I know.

So I deployed the exact same proxy contract as the one on mainnet, and pointed it to the main PoH contract on Kovan: 0x73bcce92806bce146102c44c4d9c3b9b9d745794
